What is the minimum step width required for mobile ladders?

The minimum step width required for mobile ladders is set to ensure both safety and stability for users when accessing elevated areas. A width of 16 inches strikes a balance between providing sufficient foot support while also not being overly wide, which could affect the ladder's stability. This measurement is part of safety regulations to help prevent slips and falls, ensuring that workers can safely navigate up and down the ladder while maintaining balance.

Choosing a step width smaller than 16 inches may compromise user safety, as it could lead to increased risk of slipping or losing grip while climbing, especially when carrying tools or other equipment. Wider step widths are not mandated because they may unnecessarily increase the size and weight of the ladder, making it less portable and practical for use in various settings.

Therefore, the requirement for a minimum of 16 inches reflects the balance between safety, practicality, and adherence to established guidelines in ladder design and usage.
